Electric Propulsion: The Dawn of a New Generation of Marine Power?
Technological advancement is opening new doors for hybrid and fully electric vessels.In mid-2020, the U.S. Navy accepted the delivery of the USS Zumwalt, the Navy’s first full-electric power and propulsion surface combatant. The ship’s new electric propulsion plant provides favorable efficiency coupled with a reduced total cost of ownership. The design is flexible and efficient to deliver power where it’s needed, when it’s needed. Its adoption is symbolic of a maritime future and what could be in store for other marine craft…
Kitsap Transit Gets Fed Funds for High-Speed, Low-Emission Ferry Project
As the global maritime community collectively is slowly pushed toward decarbonization, it is generally agreed that there is no ‘silver bullet’ technical solution and that progress will come in steps, led by public/private collaboration and funding.A recent development following that script is the awarding this week of federal funds to a Washington State team working to accelerate ferry technology, with the joint innovation project selected for funding from the U.S. Department of Transportation’s Federal Transit Administration.
Vendors Sought to Inform Electric Ferry Design
Skagit County Public Works and vessel designer Glosten say they are seeking technical information and cost estimates from vendors to inform design decisions related to the electrical system, the propulsion system, the shore side electrical system, and the automated charging plug of the all-electric ferry design to replace the 41-year-old M/V Guemes currently in operation on the U.S. West Coast.“This is relatively new propulsion technology – we need to make sure we get this right.
SCHOTTEL to Propel St. Lawrence Seaway Tug
German propulsion manufacturer SCHOTTEL said it has been selected to equip a newly built harbor tugboat for the Saint Lawrence Seaway Development Corporation (SLSDC) with medium-sized azimuth thrusters. The vessel is under construction at the U.S. shipyard Washburn & Doughty in Maine. The HT-60, the smallest in the harbor tug series developed by the Seattle-based naval architecture firm Glosten, is scheduled for delivery in 2021.Craig Middlebrook, Deputy Administrator of the SLSDC, said, “This new vessel will be used to carry out a variety of construction and maintenance duties for the U.S.
Partners Developing Electric Launch for Canaveral Pilots
Glosten said it is working with fellow naval architecture firm Ray Hunt Design and the Canaveral Pilots Association on a pilot/demonstration project for the design, construction and operation of an electric pilot boat.Marking a first for a pilot boat in the U.S., the vessel will feature a battery-electric propulsion system with an emergency ‘get home’ diesel engine.During the feasibility-level engineering, the team established that a Ray Hunt hull form outfitted with a Glosten…
Glosten Design for All-Electric Ferry First
Alabama's historic Gee's Bend Ferry recently entered service after being converted from geared-diesel to become the first zero-emission, electric-powered passenger/car ferry in the United States. Owned by the Alabama Department of Transportation (ALDOT) and operated by HMS Ferries, the 15-vehicle/132-passenger ferry runs on the Alabama River between Camden and Boykin, AL."As a first-of-its-kind vessel in North America, the Gee's Bend Ferry will have impact far beyond the State boarders.
Kitsap Transit's Hybrid-Electric Water Taxi
All American Marine, Inc. (AAM) built and launched a 150-passenger hybrid electric vessel for Kitsap Transit.The aluminum catamaran was designed by Glosten, Seattle, WA, and will operate during peak times on Kitsap’s Bremerton-Port Orchard or Bremerton- Annapolis routes.The 70 x 26 ft. USCG certified passenger ferry features an efficient aluminum catamaran hull, ADA access throughout the main deck, and twin BAE Systems HybriDrive propulsion systems driving fixed pitch propellers.
Glosten, Bieker Boats Design Ultra Fuel-Efficient Vessel
The provider of naval architecture and marine engineering services Glosten and marine craft builder Bieker Boats have joined forces to bring modern composite hydrofoil technology to the passenger vessel community.This collaboration draws on Bieker Boats’ years of experience designing fast foil-born boats and Glosten’s design of passenger vessels for public and private clients over the past 50 years, said a press note from Glosten."This ultra-efficient vessel requires less than half the installed power of a typical passenger catamaran, resulting in a 50% reduction in fuel consumption.
Glosten to Design Electric Ferry for Skagit County
Washington’s Skagit County has selected Seattle based naval architecture and marine engineering consultancy Glosten to design a new all-electric vehicle/passenger ferry. The new ferry will replace M/V Guemes, which has provided service between Anacortes and Guemes Island, Wash. since 1979, and is now nearing the end of its economic useful life. With a capacity of 99 passengers and 21 vehicles, the vessel forms a primary mode of transit for residents of and visitors to Guemes Island.
Glosten Designs Hybrid Ferry for Kitsap Transit
Seattle-based naval architecture and marine engineering consultancy Glosten said it has completed the design of a new passenger-only hybrid ferry for Kitsap Transit, a public transportation agency based in Bremerton, Wash. The new hybrid electric 150-passenger ferry will be the first in Puget Sound, and is expected to carry more than 350,000 passengers annually. The 70-foot-long aluminum hull catamaran will be constructed at Bellingham-based All American Marine. It will feature two BAE HybriDrive propulsion systems driving fixed pitch propellers.
MTU Powers Ice-Capable Research Vessel
MTU, a Rolls-Royce brand, was chosen to power the Sikuliaq, a U.S. academic research vessel tailor-made for oceanographic research. The Sikuliaq, one of the most advanced university research vessels in the world, is owned by the National Science Foundation (NSF) and operated by the University of Alaska Fairbanks as a part of the University-National Oceanographic Laboratory System’s academic research fleet. The Sikuliaq is powered by a total of four MTU Series 4000 Ironmen engines, two of which are MTU 16V 4000 M23S marine generator engines.
RAL, Ausenco Sandwell Team for CG Bid
One of Canada’s most storied naval architecture firms, Robert Allan Ltd., and Canada’s leading arctic and offshore engineering firm, Ausenco Sandwell, formed a joint venture -— Canada’s Arctic SAGE Team -— to bid for the design of the Canadian Coast Guard’s new flagship icebreaker. “Canada’s Arctic SAGE Team brings together the most experienced, skilled and talented team in the world on ice breaker technology,” says Robert Allan Ltd.’s Executive Chairman, Rob Allan. Prime Minister Stephen Harper announced the new icebreaker project in August of 2008. The ship, to be named CCGS John G.
Glosten Completes Study for WSF
The Glosten Associates announces completion of a feasibility study for Washington State Ferries (WSF) on converting its 144-car ferry design to liquefied natural gas (LNG) propulsion. Glosten’s study, which investigated design, economic, regulatory, and environmental issues, concluded that the conversion is both technically feasible and cost effective, although technical and regulatory challenges remain. To support the study, Glosten developed a preliminary design for both dual fuel and single fuel (LNG only) engines.
